Abstract

A method for identifying traffic information includes receiving traffic data including a first identifier, information corresponding to a prediction of an amount of congestion for a particular link, and information corresponding to a location associated with the particular link. The first identifier enables a determination of a type of the information that is included within the received traffic data. The method also includes determining a type of information included within the received traffic data based on the first identifier and determining congestion amount prediction information based on the information included in the received traffic data only if the first identifier enables a determination that the received traffic data includes a prediction related to congestion amount. The method further includes determining location information based on the information that is included in the received traffic data corresponding to the location associated with the particular link identifying traffic information based on the determined congestion amount prediction information and the determined location information.

Claims

1. A method for processing traffic data at a receiver, the method comprising:

receiving a message structure including traffic data including;

information corresponding to a prediction of an amount of congestion for a particular link and a first identifier which enables a determination that the traffic data relates to the prediction of the amount of congestion for the particular link,

information corresponding to a prediction of an average speed for the particular link and a second identifier which enables a determination that the traffic data relates to the prediction of the average speed for the particular link,

information corresponding to a current average speed for the particular link and a third identifier which enables a determination that the traffic data relates to the current average speed for the particular link,

information corresponding to a current amount of congestion for the particular link and a fourth identifier which enables a determination that the traffic data relates to the current amount of congestion for the particular link,

information corresponding to a location associated with the particular link, and

information corresponding to a message management structure including information corresponding to a generation time of information reflected in the traffic data; and

decoding the traffic data.

2. The method of claim 1, wherein the generation time included within the received message management structure relates to a plurality of message component structures that correspond to more than one of a predicted or current traffic tendency, a predicted or current amount of traffic, a predicted or current speed, or a predicted or current time to traverse a particular link.

3. The method of claim 2, wherein each message component structure further comprises an identifier specific to a type of information.

4. The method of claim 3, further comprising receiving information corresponding to a chronological indication associated with the predicted congestion amount revealed by the received information.

5. The method of claim 4, wherein the chronological indication reflects a particular time of day for which the predicted congestion amount corresponds.

6. The method of claim 4, wherein the chronological indication is reflected using the universal time co-ordinated standard.

7. The method of claim 1, wherein the predicted amount of congestion reflects an average of more than one indication of congestion amount associated with the link.

8. The method of claim 1, wherein the predicted amount of congestion reflects a weighted summation of more than one indication of congestion amount associated with the link.

9. The method of claim 1, wherein receiving information corresponding to a prediction of an amount of congestion includes receiving a value associated with a text description of an amount of congestions, and determining, with the received value, the text description.

10. The method of claim 1, wherein receiving information corresponding to a prediction of an amount of congestion includes receiving a predicted congestion amount for the link including a text descriptor.

13. The method of claim 1 wherein decoding the traffic data includes:

determining the prediction of the amount of congestion for the particular link based on the first identifier;

determining the prediction of the average speed for the particular link based on the second identifier;

determining the current average speed for the particular link based on the third identifier; and

determining the current amount of congestion for the particular link based on the fourth identifier.

14. The method of claim 1 further comprising enabling, based on the decoded traffic data, display of one or more of the prediction of the amount of congestion for the particular link, the prediction of the average speed for the particular link, the current average speed for the particular link, and the current amount of congestion for the particular link.

11. An apparatus for processing traffic data, the apparatus comprising:

a receiver configured to receive a message structure including traffic data including;

information corresponding to a prediction of an amount of congestion for a particular link and a first identifier which enables a determination that the traffic data relates to the prediction of the amount of congestion for the particular link,

information corresponding to a prediction of average speed of the particular link and a second identifier which enables a determination that the traffic data relates to the prediction of the average speed for the particular link,

information corresponding to a current average speed of the particular link and a third identifier which enables a determination that the traffic data relates to the current average speed for the particular link,

information corresponding to a current amount of congestion for the particular link and a fourth identifier which enables a determination that the traffic data relates to the current amount of congestion for the particular link,

information corresponding to a location associated with the particular link, and

information corresponding to a message management structure including information corresponding to a generation time of information reflected in the traffic data; and

a decoder configured to decode the received traffic data.

12. The apparatus of claim 11, wherein the traffic data includes information corresponding to a version number of information reflected in the traffic data.
